Question Best Cbe For 2.5i's

alright guys, i have a 2.5i 2007 that already has a custom one piece cbe, it rumbles, but not to what i'm looking for, just looking for suggestions on the BEST cbe system for a 2.5i.

i was gonna go with invidia n1 race exhaust but looking into it, it will kill my torque at low end but increase my top, honestly... i dont wanna lose low end more than i have installing the injen full cai system. so please... bring on the suggestions.

thanks!

A stock cbe is probably the best. Changing it wont do much in terms of adding power. However, I love my stromung. Try to pick one up used or something. btw, you have an 07 with stock equal length headers so you wont really rumble no matter what catback you get.

you wont get a rumble without UEL and custom with a resonator i think would be the best price and sound overall. Stromungs a lil on the expensive side for me.

stromung! borla is a good second pick. also, if u have money, get the borla/replics header and a random tech/other high flow cat. u will loose the resonator with an aftermarket CBE, but u can always weld on in. i have the borla header, random tech cat, and stromung CBE and love the sound it makes.

Heres a bit of a low buck solution that I have actually done. I put on a DynoMax Bullet muffler. I had the entire header back custom made with mandrel bends and had them put on that muffler. After much research I found that it is the highest flowing muffler around, even more than open headers. Then just ran the exhaust beyond the bumper a bit. Since you are doing just Cat-Back then only go that far. Or you could get a high flow cat like a Cat-Co and go all the way. By the by this was on a 96' Brighton with the EJ18, and toque picked up nicely.
