When I was considering my custom set-up this is what I was down to:

https://www.magnaflow.com/automotive...oval/products/

https://www.borla.com/products/mufflers/proxs.html

https://www.borla.com/products/xr1.html

https://www.flowmastermufflers.com/street-mufflers/
^ 40 and 44 series

For what it's worth, my anticipated set-up included the resonated X-pipe and all of the above sounded good to me.

Of course I didn't go the custom route for the "learning experience", even though that's what it's turned into. I ****ed my exhaust up, plain and simple. I was impulsive and tried to get better sound for cheap, which went as well as one could expect.

The thing is, I originally planned on never touching my G and keeping it bone stock, but that stock exhaust drove me nuts at high revs - just sounded raspy and weak. My goal was to get a throatier sounding exhaust that wasn't too loud and had no rasp or drone. For what I've put in and maybe a tad more, I could've gotten the Topspeed exhaust and called it quits until I saved up for a premium CBE, but hindsight and all.

So right now I'm slowly saving for a premium CBE, and by slowly I mean I haven't saved up anything except the $300 I have left over from my tax return. Honestly, I don't see myself wanting to spend that sort of money in mods anytime soon, at least not for another year or two. So one must ask himself: Do I live with my **** up for the next year or two? Or do I make an attempt at a short win and have a nicer sounding exhaust until I install a premium CBE?

I lean towards the latter, as I have to drive the damn thing every day. I know I would possibly be spending $300 bucks to further botch my exhaust, but I've done a good amount of research, as I did with the resonated x-pipe (which helped a lot). In addition to the to 2.25" piping and Magnaflow resonated x-pipe I currently have, I'm confident that some decent resonators/mufflers would clean the exhaust up. The new exhaust shop I've found is inexpensive and if I do botch my exhaust even further by installing the resonators and mufflers, it's very cheap to return the exhaust to where it's at now ($50). If that happens, I will sell/return the resonators/mufflers and leave my exhaust alone until I install a premium CBE.

So given my current situation, what would y'all recommend to clean my exhaust up? Resonators and mufflers makes the most sense to me, but I've seen people do mufflers instead of resonators then straight piping where the muffler would go. It sounds nice but a bit too loud, and I could see that setup droning too.

Thanks, I've viewed the Borla's and IMO they sound the nicest, but they also seem the loudest.

If you had to choose, which one would you have gone with? What setup do you have currently?

I'm not sure how RMB's experience was, but every Borla exhaust I've ever owned had absolutely god-awful drone. I think you benefit here from just checking out mufflers and resonators.

If you aren't totally hell-bent on Borla, Tanabe axle-backs and Vibrant 1790 resonators (12 inch) are a really good combination that isn't too loud.

​​​​​​Borla sounds nice but I'm not really leaning towards them, mainly because they're a bit expensive. Tanabes are more than I'm looking to spend and I'm not sure I can get past the looks, but they sound great.

I wish there were more videos of a similar Magnaflow setup. They are well reviewed and priced - they sound good on other V6's too.

The price tag on the Tanabe's is what halted me from grabbing them. Y-back for that price and I'd not have thought twice. Just cans.....eh. Plus, The amount of guys that have regret and state the set-up is quieter than stock turned me off. Borla is the loudest without question. Flowmaster has a nice deep grumble to them but the quality seems eh and it makes the G sound too...American?

The Magnaflow chambered set-up is what I was leaning towards. I've yet to pull the trigger though....I'm way too indecisive right now but Magnaflow seems to give that right in the middle sound where it's low and throaty then cuts loose above 4000 RPMs.

That and the fact I'd have to go to a shop 30 minutes away during the week and I just simply haven't had a moment since I've started considering an exhaust. In all honesty, I'll probably grab coil overs first before worrying about the exhaust...I've also been eyeing some wheels also.

Keeping the car stock... That was me once... Lasted close to 2 years.

Since you want to eventually get a premium system, I think it's more worthwhile to minimize your current cost. If you can add another resonator or muffler for real cheap, that can be a good option. I think it will only improve your sound.

But if it's going to cost you over $200, you may want to consider shopping for a used tanabe for like $400 or a topspeed axleback so you can resell it later on. I'm not sure how well you're going to be able to sell some of the custom parts you've made.

I just checked online for topspeed prices and they seem expensive right now. Like $100 more expensive than what I remember. I feel like it's because we're right before Chinese New Years. I think price again within 2 months.

i initially went with the topspeed exhaust and loved it. I then got Berk resonated test pipes and started looking at available y-pipes. There was actually only 2 that came up that I thought were worth it. One was the Motordyne XYZ and the other one was the Tomei, all the others seemed no different then the ones you find on ebay ( Megan, AAM, TopSpeed etc ) I carefully thought about it and said why am I spending $600 bucks on a y-pipe. I scrapped the idea and had an x-pipe made from my test-pipes into the X-pipe and I had the flanges cut on my mid-pipe and I kept the resonators from the topspeed exhaust. So I have 60mm piping starting with the testpipes all the way through to the mufflers. My total cost was $750 (500 on the exhaust & 250 to get all the piping made and xpipe welded ) and sounds great and no complaints really. A bit of rasp about 3000-3500 but thats about it. Better than dropping 1500 on a cat-back for bragging rights.

If I could go another route I'd go Tomei single exit and pair it with Tomei Y-pipe but not going to drop money like that on something on my car thats already done.

My thoughts are similar to yours. I think the Tanabe is too expensive, even used, and I've heard from more than a few people that Borla's drone, which is a huge turnoff for me. I've seen very few good sounding Flowmaster setups as well.

IMO the Magnaflows are the best bang for your buck, but I really want someone with a Magnaflow setup to chime in. I've been eyeing two different Magnaflow mufflers and I'm really not sure why one is $20 bucks more:

https://www.summitracing.com/parts/mpe-13215

https://www.summitracing.com/parts/mpe-11225/overview/

I'm still indecisive as well and will do a bit more research before I pull the trigger on anything, but it will be soon (next month or so). I'll post some vids with whatever setup I go with and maybe it can help your decision.

Damn, you made it way further than I did!

And I want to keep it around $300 including install - which should be around $100, so I'm really not looking to spend more than $200-$250 on parts alone. I doubt I could get a used Tanabe or Topspeed exhaust for that price. But honestly, even if I could, I can't get past the looks. For some reason, those types of cans look decent on G's with larger wheels and dropped suspension, but they look out of place on stock G's - it's like the visual weight is shifted too far backwards.

So between the cost and looks, I haven't really considered any axlebacks. I know I may have issues selling or returning mufflers and resonators (Vibrant resonators shouldn't be hard to sell though), but I can't see higher quality resonators and mufflers making my G sound any worse than it does.

One is the straight through while the other is a chambered set-up. The chambered one has more of a 'F1" sound to it. The straight through is the classic Magnaflow muffler; know what you're getting.

The chambered one had a more aggressive sound which is why I liked it. There's a post a few pages back where someone has a chambered set-up and it sounded pretty good. I figured if I paired it with the resonated X pipe (what you have) it would tame it down some where it was very aggressive at WOT but not over the top.

Custom 2.25" Catback Exhaust

Exhaust is finished and I'm liking it quite a bit. It's not too loud when just cruising around and it's very aggressive sounding at full throttle. My only complaint is that it drones a bit from 2k-3k, which is annoying. Will drone decrease as the exhaust breaks in?

The setup as of now is stock cats with 2.25" piping from midpipe to muffler. I then added:
  • 2.25" Magnaflow resonated x pipe https://www.summitracing.com/parts/mpe-11385
  • 2.25" 12" Vibrant Resonators https://www.summitracing.com/parts/vpe-1790
  • 2.25" Magnaflow 3 chamber muffler https://www.summitracing.com/parts/mpe-13215
If you don't go through an "experimentation" stage like I did and just buy what I've listed above, including labor this setup costs $550. Not too shabby for how good it sounds (minus the bit of drone).

Here are some clips:

Sounds nice just sitting there are revving. And it doesn't sound bad driving it under load, just kind of muted. Get rid of those OEM cats, and it will come alive.

Thank you, I was trying some different tags on my phone but they weren't working. How did you embed the videos?
