which kind of system is better? does the cat back exhaust provide more hp gains? if so... which exhaust would you guys recommend?

 

Well, cat back goes from the catlytic converter back. Now if the diameter of the piping stays the same as stock with new mufflers there should be a minimal increase in power. But if you do bigger piping, you would gain power but loose some torque in the process.

 

whcih system would you get then? the cat or axle ?

 

I would get the cat-back systems. There are many nice cat-backs for our cars...but this is on your own personal taste.

 

I'm selling a set of Comptechs at a good price if you are interested.

 

I got the Tanabe Hyper Medallion Catback Exhaust System! I like it and it runs good with great sound!

 

post pics!!!!

 

Here's my Tanabe raised and extended to be flush with the rear bumper. They are loud when stock, I added a resonator so they now sound mean!!!

 

so which one is the MOST QUIET cat-back for our car?

 

Apex'i world sport

 

Which exhausts sound deep and muscle-car like with the most HP gain and what are all of the application choices for our cars?
