3" catback

[The Broken Regal]

Well I've thrown it out there with a few people at lukes, but i'd like to hear what others have to say

have TOGs that go down to 2.5.... looking at getting some sort of 3" catback that starts 2.5 and expands... i could feel a difference when I did that on my old white car

reason I ask is, given my gears, 1st gear on the street is pretty much worthless anyways and i know I'm giving up speed up top... figured i could let go of some trq and then gain some top-end?

keep in mind, im still on a 3.2 and the tires just blow off even at a prepped track unless I drop em to 24-25lbs and I have to be very careful! If I ever go down to a 2.8, might as well just run slicks all the time, as first will just spin

Why not 3" the whole way?

 

[PANDA]

Only thing keeping me from taking off my stock catback is the sound. 3800's sound like shit.

 

[The Broken Regal]

unless i was turbo and/or pushing 400whp, i know that full 3" is way overkill... im just going by how it changed my old white gs with simple bolt-ons... and how if I did the exact same thing on the current setup, that it might be beneficial

and we know where your bottleneck is


you have a positive displacement blower remove the restriction, these mtors have plenty of bottom end to trade it for a bit more up top

 

[Handsome Jesus]

i know mine has different gears but you can drive it next week to see if there is a huge difference?

you might even be able to use a slight reduction in torque to get a little more traction.

i was hoping for more of the, hey at the track day we'll swap my single 3" onto your car and see what happens, kinda thing

i mean you got those mitts and all...

but really, i'd pay you to let me do that and see what happens, even if it is just a single mandrel 3"

 

[Handsome Jesus]

Well, I hope you have paceshitters, because that's the only way to get my exhaust onto your car. it would involve dropping the pacesetter downpipe. Rather than the typical 2 bolt flange that stock exhaust has, I put in a 3" v-band.

Let me know man. it's worth a shot.

Dual 4" with stacks out the trunk. Get some!

i wanted DD to grab some 3.5" stuff for his super single exhaust for his super6

 

[DanJ]

404 super6 not found

 

[Handsome Jesus]

lol 3.5" would have been interesting to make fit under the car. and expensive.

also muffler choices are severely limited.

 

[M@]

noisy exhaust was one of the biggest factors leading to me hating the fuck out of my regal, and there's no such thing as a quiet 3" system.

3800s drone, and sound like asshole, and this system 100% will NOT gain you any power at all. Your shit will be loud, people will point and laugh at your honda sounding buick, your exhaust will weigh more, and your ears will hurt after any trip longer than 30 miles. Fuckthatalot.

ah there you are lol

um so whats with this common misconception being thrown around that with FI motor cars, the more free flowing the exhaust, the better?

I agree with this

i have a 3" catback into magnaflow mufflers and no res. i have yet to have someone tell me it sounds like shit. but then again im happy with anything that sounds better then a civic.

 

[Handsome Jesus]

Yeah I guess I do too.

I love how the car sounds, but really it is still slow, so it doesn't need to be that loud. my car is quiet cruising but accelerating is loud as hell.

just go turbo kevin. that makes the best muffler for a 3" exhaust. perfect logic right?

My car is loud enough to go 10s. too bad it only goes 14s.

 

[Bob Kazamakis]

my car is quiet with a full 3" exhaust, no cat and see-right-thru muffler

eh, i talked to a guy on the regal boards about twin-charging.. too bad even though its not much more stuff, its still like 4k for the kit, yikes

idk, how much turbo stuff you got left over from the black car?

 

[Handsome Jesus]

haha not much... just the piping bullshit really.

there is a gy selling a set of brand new t66 turbos on chitown racing... 850 for the pair! unbelieveable deal.

I would do it but I really need a trans first. definitely decided on that. can't really buy another car so I might as well make this one more reliable... and faster.

 

[Fish]

My 3" is fairly quiet. I think it varies on muffler choice as well. Plus I have the big ole resonator that came with it, and I even bought a resonated tip. Probably does a bit less then nothing.

 

[Handsome Jesus]

the resonated tip worked awesome on my car... it's some fancy magnaflow oval thing.

I hope it isnt the same as yours fish... cause that would suck sorta.

we'd have to have to fight over who did it first. :gfight:

 

[M@]

With a turbo, sure, I'd agree completely.

With a blower, noop.
These things flow well on the exhaust side out of the box (well, the heads at least). Throw some headers on it, and you're good. The downstream really doesn't affect power production much. I really don't have a good explanation for it (I'm sure I could come up with something but whatev), but I've seen it time and again. Blower cars with cutouts picking up almost zero power, etc.

I suppose we're talking GS exhaust here though, and if that's the case, then yes, it sucks, badly in comparison to the GP system it seems. I'd recommend going to a stock GP system, at least from the Y back, or a single muff 2.5" system, with a big res. 2.5 will flow plenty, will be lighter, and will sound less like asshole...

 

[M@]

anyone who believes any 3800 sounds decent (without a turbo on it) needs to get their ears checked, or at the very least, hear it from outside the car, i.e. following behind while someone else drives it.

NA and blower 3800s do not sound good, ever, period. It's one baby step above your average ricer sound...barf.

 

[Eagle]

You're telling me. The whine is already growing old.... the rest of the sound is like the sound beer makes when it goes skunk. :FAIL:
