i read through all the threads about exhaust and there seem to be a whole lot of info.i plan on getting a custom set up which i will delete the stockcat.converter since where i live it would not matter law wise, then where the cat.used to be i was going to replace it with a magnaflow muffler,delete the resinator with at the end of theexhausta universal muffler at the tip one that looks like a bazooka.the size of the exhaust will be 2.5 and i am hoping for a low deep sound.please let me know what you all think about this setup and what will be the best without losing hp.-thank you

 

2.5" is way too big.

 

from what i read maybe i am reading it all wrong was that 2.5 is the way to go(2 1/2)-(3)

 

put in a regular catback system and put in a high flow cat. thats pretty much wat you just explained. lol. should cost only $300

 

2.25 is about the biggest piping you want on a N/A car

 

If you put a muffler where the cat was, you will fry it. Mufflers aren't built to handle the temperatures that the cat sees. If you don't need to have a cat, you can get long tube, 4-2-1 race headers, but for normal driving, the stock manifold will give you more low-end torque. Alternately, you can replace the cat with a test pipe. As mentioned, the best setup for you is a pre-made 2.25" cat-back ... a 2" would be good also.

Your engine would use a 2.5-3" system only if turbocharged.

 

im running 2.25 with high flow cat converter and a glasspack resonator...you will definately notice better accelaration

 

soooo... i should go for 3", right? im about to do this... but not sure... cops are very annoying here, there's some kind of "law" about not modifying the exhaust... but whatever... should i got 3" or 2.5"?

 

Kevin .... how much boost are you running??
