Ok so i have purchased the catback from a stock SC. now i know the piping is plenty bigger, nice to open it up a bit. but im wondering about the restrictiveness from the stock muffler. My thoughts were, since it was a supercharged motor/(performance vehicle) that the muffler would be a pretty high flow one. my brother and dad have both said that i should cut that one off the exhaust and buy an aftermarket, like a magnaflow. Thoughts anyone. and if a new muffler, which brand?

 

umm i mean u can..i would just replace the whole catback. with a aftermarket..i have the GMPP exhaust..the stock resonator n muffler are both restrictive..but what makes it flow better is the bigger pipes..but i would get a whole different catback.

 

for the money that has already been spent on it, it seems worth it. i got alot bigger piping as compared to the peashooter size of the 2.2. my real question i guess then is will i see any gain whatsoever with replacing the muffler with an aftermarket one.

 

not really..going to be very minimal..only difference would be sound.

 

mmk thx, i have heard the sc exhaust on a 2.2 and i like the sound, so if no extra gains, no point. thanks again.

 

I put a SS/SC cat back on mine. For the money I think its the best thing. It's going to flow better then the stock pipe and because its factory its not going to sound like a ricer. Only problem is the tailpipe drops about 2 or 3 inches, need to put some straight pipe from the muffler for it to look right.

 

Keep the stock SS/SC muffler!! No drop here.

 

you should try and get a stock LSJ header and downpipe, I got mine for free from a guy who went aftermarket

 

He has an 07, so no need for the SS/SC exhaust manifold/header. But, the SS/SC downpipe would help.

 

there are some 2.2 guys loadin up on ss/sc parts..and getting some good gains on these mods...but yeah u def have to cut the pipe and have it coming out straight like in the pic above

 

No cutting there, that's the stock pipe/muffler. Just a creative installation.

 

hey Stl06LS that looks extremely nice nice on ur ride, i have the full lsj exhaust header,downpipe,catback the only problem is i dont have the chrome tip it was cut off for another setup, does anyone know if i buy the tip that comes with the gmpp catback if it will fit

 

Crate Engine Depot sells them.

 

so does the 2007 2.2L and the ss/sc have the same manifold?

 

Yes. They are both the same.

 

Manifold is the same.. so whats the 07 DP as compared to the ss/sc DP? same there too?

 

Nope the lsj is still larger
