So much quality work in this thread! I wish I had more experience with welding so i could make my own exhaust.

vicroll91 · 12-09-2010, 07:51 AM

heres 04 LGT exhaust. Piping is mostly stock, just replaced some of the piping at the axle, then welded on a modified eBay muffler (Welded a resonated tip on the end for sound/aesthetics) Lemme know what ya think!

New owner of a 2010 wrx sedan and looking into a custom turbo back exhaust. I was curious as where i can get a prefabricated vf52 output flange? If this is possible? Also a recommendation of a muffler, there are too many choices out there. The only reason for a custom exhaust is due to the fact my stock exhaust scraps my very steep drive way. I would hate to scratch up an expensive bolt on exhaust.

Any advice will help!

Also, I'm really interested in making a side exit exhaust for the wagon too.

Just to clarify, my Sentra is turbocharged, and I used the race muffler before the resonator.

hopefully i have something to add to the mix soon

^i take it the edges of all the pipes were beveled. I assume that is what i'm looking at. Does it make it easier to get a good weld?

scubydrew · 02-09-2011, 02:55 PM

That's where the strength comes from. It also allows a place for the filler to lay into rather then on top the piece.

Crazy_pilot · 02-09-2011, 03:05 PM

What tool do you use to bevel the edges when you cut the pipes/bends to the sizes needed?

Mock up of a turboxs 4" downpipe to fit 08 wrx sedan turboxs catback.

Hey, for those of you running custom exhausts/ mufflers, I was wondering if you can give me some advice in picking a muffler for my custom exhaust. It will be 3" piping and I want it to be loud, but not like super illegal loud, I want it to have some umph. I was thinking dynomax or something like this.

I really don't want to break the bank with mufflers, but also don't want to cheap out on my car, so if someone can point me in a direction, that would be awesome!

Also saw this no name one, but seems good in terms of it being straight through and looks similar to other name brand ones, but again, don't want to buy a poor quality product on a brand new car

biggreen96 · 02-21-2011, 06:04 PM

Magnaflow oval. It's a straight through design so it flows well and has a good tone. Search youtube for some clips. It's only about 75 bucks too.

thebigevilfoot · 02-21-2011, 07:13 PM

I'll check it out. Thanks!

Then just go buy about 10ft of 3inch stainless pipe and get all the bends you need, weld the flange on and run straight pipe. It cost me $50 to run straight pipe to my rear end.

thebigevilfoot · 02-21-2011, 11:07 PM

But wouldn't that just be disgustingly loud? I was thinking 3 inches from the turbo with a resonator and 2 mufflers...

yo_its_ok · 02-24-2011, 07:47 AM

lol depends on person definitions of being loud, but legal ??
3" from turbo to a Vibrant Ultra Quiet resonator, and choose whatever muffler you want or you can purchase Thermal R&D muffler, which is fairly quiet by itself.

Scargod · 03-02-2011, 04:22 PM

As I posted on the New England Chapter forum, I'm looking for a recommendation for a shop that can fab exhaust parts for my 2011 STI sedan. Muffler shop or performance shop; I don't care.

I just bought a TurboXS Cat-Back Exhaust system, TXS-W08S-CBE, and I'm awaiting its arrival. It has a completely 3" "Y" pipe. I'm going to try this new exhaust cat-back, as is, before I decide whether I will fab some pipes so I can bolt up the Spintech mufflers I've also purchased.
I've got to pass the sound level restrictions for CART and FCSCC autocrosses as well as Lime Rock. I haven't a clue whether the TurboXS system will pass or whether I can get more power with the Spintechs... I am at Stage 2 with a Cobb catted downpipe and Cobb SF Intake.

I am near Seymour, so anything in the Naugatuck Valley, New Haven, central CT or even the Hartford area would be good.
Or, are there any DIY shops or clubs with a TIG welder I can use? I can machine, fab and weld... but I no longer have metal-working capability in my garage-shop.

Lastly, has anyone eliminated the 2-1/2" neckdown on 3" downpipes? Seems silly to have it transition to 2-1/2" only to go back to 3" for the cat-back! What's the best type of connector for doing this... V band?

Story: When I was 20 I machined some flanges and welded up dual intakes for my VW out of tree lamp tubing. It held together. @30 I used to Tig really thin SS just for practice.

bmw325ix · 09-29-2011, 09:07 AM

For my '08 STI, some TIG welding practice, everything is stainless

3" Catless downpipe for a rotated turbo V-Band flange

2.5" cat back with a super light weight muffler, turn down tip

zmillz · 09-30-2011, 12:01 AM
