2-Pipe/perforated exhaust Mod Shops in Bay Area?

cabeerman · 10-28-2021, 10:33 AM

Anybody near SF have their exhaust modded with the 2 pipe adjustment? If so, is there a shop you recommend and rough cost? Looking to sell my Magnaflow cat back exhaust (came with the car...) and return back to stock with this mod done. Would also like to hear it if anybody has it done with their stock x-pipe!

Thanks!

You need stock muffer?

What's wrong with the Magnaflow cat back exhaust? too loud?

Yeah there is a shop here in San Jose that can do the mod.

We got a few guys here that have done it. I'll have to message them to see if they got time.

Have a stock muffler. The magnaflow actually sounds very good with spirited driving, and if thats all I was doing I would totally keep it. Looks good too compared to a lot of the others on the market.

But as a DD around SF, the drone ~2K just isn't sustainable.

True, all aftermarket exhaust have drone.

Wait till you hear mine!

I don't even know what I have, it's just stupid loud.

I had Todd modify my exhaust with 4 pipe mod at Exhaust Works in Belmont. It was $300 back in 2017. I don't know what it cost now. He uses a plasma cutter and makes pretty quick work of it.

Everyone goes to minute muffler. Thats where i went

osukf09 · 10-31-2021, 11:00 AM

Minute muffler in dublin has done a ton of these (did my 4 pipe mod, as well)

Golden Auto in SF may be worth contacting also
