Default Good Exhaust Shop

I live on the MA/NH (near Nashua)Border & looking for a knowledgable exhaust shop.

My STI came with a full APS racing exhaust on it, & they no longer do business in America. 3.5" pipe all the way back. The car was built for the track, but for a summer car, it is just too damned loud. I've never heard an exhaust this loud. When you get on it, it's downright pulverizing. It doesn't help that my car has a destroked motor & doesn't redline till 11k rpm.

Very few 3.5" axle backs out there (any?) that are not the same deal. The outside of the car is a sleeper. No wing, no hood scoop. Unlike many, I want the quietest exhaust possible, but with the best flow. I know those really don't go together so I'm looking for a good compromise.

The shops I have called are either useless or out of business. I love the response "Yeah, well, just pick out an exhaust, & we can install it for you." I can install it stupid, I don't know what exhaust to get. I need a real shop who knows what the hell they are doing, & has experience with this...any recommendations?

For your year you could try to find a prodrive or just use the stock STi axelback with the aftermarket midpipe.

11k RPM EJ?

Anyways, just gut the stock STi axleback. It's very quiet and will flow just fine.

No mom and pop exhaust shop is gonna give you an answer for an exhaust for an STI. Just get any 3" dia catback exhaust and throw it on.

Prodrive is very nice and I think I saw one forsale in NESIC. I really like MadDad products and they are also from MA. You'll never get it as quiet as you want.

This is what I was looking for, thank you.

& yes, 11K redline on an EJ255. It's a destroked motor. Look it up, youtube it, you can see video's of it pinned to 9k & keep on going.

A stock STI is not going to match up to a 3.5" flange very well. I need at least a 3"

I know I'll never get stock quiet, but I don't want racing volume either.

We have had a few customers making over 500whp with the Invidia Q300. Not super-quiet, but the best you're really going to get for a full 3" stock-style exhaust with a real muffler.

You should also know that just about any catback out there is NOT going to mate up to the APS downpipe, they are made so that you must use the whole turboback, unless you want to modify one end or the other. Generally APS systems are sold as a complete turboback for this reason. Give us a call at the shop if you want to go over it, we have installed most of the exhausts on the market, including both (now discontinued) APS turbobacks, Prodrive (also disco'd AFAIK), and the various Mad Dad systems. If you want a custom exhaust we can do that as well, we do plenty of custom fabrication with different grades of stainless, we also do aluminium and we've done titanium as well, we hand TIG weld everything with quality parts.

I don't believe it's an APS DP, It looks custom. I'll check it out further tomorrow.

What I was hoping for was just to change the axle back. Mad dad makes a 3" and something could be done there.

I'll give you a call tomorrow.

Yeah, it's not an APS DP, it's custom.

Car looks amazing based on that video. Hopefully you find an exhaust that works. Good luck.
