FD Exhaust size and fitments

[MyBoyBlue]

What size pipes are you running all the way back?
What muffler?
How many tips?
How big are the tips?
Would you use your setup for a daily driver?


I'm going to be getting a custom exhaust with my setup and want to do true dual all the way back but the shop can only bend 2.5" and I don't want to lose performance. Of course a single 2.5" won't be enough but it made me curious what everyone else was running.
I asked about the muffler because I want the quietest I can get without losing performance; yeah, I know it will never be quiet.


Edit: Forgot my sig doesn't have mods anymore. LS2, custom true equal length long tube headers, 228/232 cam, ported & polished heads, ported intake manifold, Holley throttle body, blah blah blah.

i have hinson long tubes down to 2.75 inch Y pipe, then to 3 or 3.5 single to a who knows what coffee can. i would DD mine little loud but it is something you want to be a little loud.

JTR 1-3/4" Longtubes
2-1/2" Tubes merge together at Y-pipe
3" Single pipe to the 3" In-Out Magnaflow Single Tip Muffler

Wish I could have gone with 3-1/2" Y-pipe to muffler... but the shop that did the work didn't have that capability.  Either way, Sounds amazing!

Hinson mids
3"- Y pipe Custom pancake pipe compliments of a speed bump

3.5"- From y to catback
95mm~ 3.74"- Apexi catback

Entire setup has the bling factor but was expensive and overkill IMO.

How did you get the long tubes to fit with the automatic???

Hinson's headers aren't real long tubes, at least the ones that BAD-LSX has aren't.   They're a long mid-length header.

[mrls1]

That what I assumed because I am running the mids with the 4l60e.

I have mine heading to the fabricator tomorrow.  Here's the set up.

JTR 1 7/8 with 3" collectors > Mandrel bent 3" pipe >
Magnaflow Muffler 2 In/1 Out (Internally this is a Y-Pipe) with 3" inlets and 3" outlet (Mounted in the trans tunnel) >
Mandel Bent 3" pipe to PFS Cat Back

Should be relatively quiet and free flowing

Sound clips? I've been eyeing that exhaust

[mrls1]

Sounds NASTY especially with the trak cam that's in the car. Still waiting on the pin kit to get here for the crank then I'll get some videos for you guys!

[Gearhead]

hows that oval tubing flow? i hope your changing it ....shit looks like it will choke

[mrls1]

No other way getting around it. The damn tranny pan is screwing me when it comes to exhaust!

[Gearhead]

i call bs....just like on the driver side of a f body.. get some true oval tubing...

spin tech stuff baby.. i need to do some systems with that stuff on it..then every one will want it

[mrls1]

Waiiiiit. That isn't true oval tubing????? Damn they got me again!

[Gearhead]
