Thread: AZ Phx Stock Internals L36 3" Catted Downpipe for deeper sound ???

I HAVE A FWI, stock downpipe with cat and u bend, but magnaflow glasspack in place if resonator and 2 magnaflow street dtm mufflers out back. I was wondering if the 3 inch dp woukd make my exhaust sound deeper and more burbly, like what a downpipe did to my buds caliber srt4. I k ow its i4 and turbo but my car already has a smooth deepish sound now but was wondering if the 3 inch catted dp would make it sound even more deeper? I know ppl say the 3inch dp is bad for power but ive seen ppl say that it just moves the power higher in the powerband. Any input is appreciated! !!

I would but im only doing this for bow because my cat is rattling

I will eventually but for now i have other things like the parking brake shoes and tierods lol but i think im just gonna do the 3 inch magnaflow cat zzp downpipe

you can do headers for $200

you just ninja'd me ILoveGM but yea everything you said about the headers vs DP is correct

Yea except trying to find a kit with the cat for under 240 dollars too? Its not happening. So thats why im just going to do a zzp catted dp. Either 2.5 or 3 inch. I was wondering if anybody else has done 3 inch catted dp or no cst on L36?

Because Phx, Az requires a Cat

So 3 inch dp or 2.5 inch? Lol

For 1996 and up they plug into the obd2 port and do a mirror check of the vehicle underneath
