My 08 sport 2.4L's exhaust is obviously really new... So i dont want to replace the entire exhaust but just want to get a little bit more sound, i'm a big fan of borla and i think i'm thinking about just buying a Borla Muffler ( about 150.00 ) and then put a stainless tip on it to look like the stock one...


my question is... how much sound will i get from just swaping the muffler??

AND will it cause any problems with my motor? or sensors?? cuz i have bad luck with that **** loll

 

Sound depends on the muffler you buy, each one will sound sdifferent and be louder or quieter. I believe Borla makes the GMPP exhausts so it should sound nice. Most people like the sound of a Magnaflow muffler on the stock exhaust. I havent heard either just going off what Ive read around here, just giving ya a lil info. And a muffler should defiantly not throw a code, all it does it "muffle" the sound it has no effect on the engine or any sensors.

 

^agreed i have magnaflow 2 of my last 3 cars love it life time warranty. and WILL NOT THROW ANY CODES

 

get the magnaflow part #11255... it will give you a nice deep tone, make it a lil louder(but not obnoxious), and best of all it wont sound like a bunch of pissed off bees.

 

150 for a muffler...waste of money to me. i would go with a catback better bends no bottle necks and sounds nice IMO. Borla are nice mufflers tho.

 

I went from stock to just a straight thru muffler on mine, and it got real loud. So I'd suggest going with a Magnaflow if you don't wanna be waking up your neighbors. Plus, the Magnaflow sounds really nice.

 

wakeing up the neighbors is totally me :] they wouldnt have it any other way lol, what size is the stock pipe ? so i know what size muffler to buy??

 

I'm not sure what ur's is...2.25 maybe? Mines 2.5 I think. I dunno, took it to a muffler shop and let them have at it lol

 

mines an 08 sport 2.4 L idk if they ahve the same exhaust as teh SC or not..

 

I don't think so. I think yours is a 2.25 exhaust and mines a 2.5. Either way tho, take it to the local muffler putter on'er guys and they'll tell ya lol

 

i think the ss/sc is actually 2.25 and the 2.4 is 2"... i put a 2.5" magnaflow on my stock exhaust and you could tell the pipes coming off the muffler where a lil bigger than the exhaust pipes

 

'07 Factory Part Numbers:

Pipe, Exh, Reso, LSJ PN 15887503
Pipe, Exh, Reso, LE5 PN 15887503

Muffler, Exh, W/Tail Pipe, LSJ, PN 15283439
Muffler, Exh, W/Tail Pipe, LE5, PN 15283439

Notice anything?

 

They looks like the same PN...Oh what do i win!!!lol
The exhaust on the LSJ/LE5 is 2.5" all the way to the rear axel, then it shrinks to 2.25" over the axle to the muffler

 

Ding, Ding, Ding...We have a winner!!!

 

I was just guessing, I didn't know for sure lol I'm going 3in, so I don't care what stock is

 

exactly.

which is why I had my muff man cut from the axel and put on 2.5 mandrel bent pipe with megan muffler. Dont know what performance gain over stock was with just the pipe since I did it with the muffler same time, but there was a nice difference.

 

o ya. i forgot about that it gets smaller at the axel, been a while since ive delt w/ it.
the part # i listed is 2.25"

 

It's the offset one? I thought the inlet and outlet had to line up on our cars?

 

not when welding..
