OK first I dont want an exhaust (catback) for performance, I want a good sound for my cobalt thats it. But i still want a full catback.

So I was thinking about Magnaflow but I'm starting to find it too much subtle...

I dont want to be too loud cause I know it will annoy me.

So If you could tell me :

1- Who has the best sound

2- Who has the best sound quality/money wise

No straight pipe, its not a choice for me cause police are annoying here.

And could u tell me if there's any changes in performence btw dealers since I dont know much about this.

 

honestly im considering the tsudo cat back its cheaper than most but sounds great and thats what im looking for nuthin to loud

 

get whatever catback you like. if its too loud, just buy a resonator and weld it in. easy fix.

 

^^^ this works also lol

 

What's the stock pipe size for the LAP exhaust?

 

stick size is only two inches. maybe 2.25 if you're lucky. If you want a decent sound, go with the tsudo catback. it seems to be the most deep tone without that ricey sound compared to other systems. if that don't work for you, get the ss exhaust. that's what I gto and i absolutely love it, i got the performance i was looking for at a lower cost with a great tone.

 

on my 07 lt I ran a CA header with a 3in collector and 2.5in cat less DP and 2.5 in no resonator to the stock muffler. Defiantly sounded different and a little performance increase. Best part was I only had to pay for the header, I had a friend that owed me and he worked at a muffler shop so the pipe and exhaust work were free.

 

I have just the Magnaflow muffler on mine and i love it. Sounds real nice, not loud at all. It's only semi loud when you get on it. I may just record it and put it on youtube for you to hear if i have time today.
