Which cat back exhaust?

Recommended Posts

I would like to know your opinions on which cat back exhaust I should run on my black Uk tt6 it’s completly stock apart from the cat back system (I do have the stock system but quite like the look of a nice stainless back box) I have both a HKS Super Dragger or a Blitz Nurspec without the baffle also I know they will not be deafening because of the cats but which would be louder?

I have hks hi power silent t's ridiculously loud, if I was doing it again I'd get something twin piped or quad pipe both sides and baffles.

 

Thank you for your reply am I correct you are running 1st and 2nd decat as it will be loud then.

It’s about the look too for me the hks super dragger back box looks so right but the blitz is seems far superior in build quality especially as it’s all stainless.

Both these systems are a single pipe I think the na nurspec system is a twin pipe/box system.

First decat and mid pipe - http://www.mkivsupra.net/vbb/showthread.php?338434-TB-Developments-TT-Decat-Pipes

 

Exhaust system - http://www.mkivsupra.net/vbb/showthread.php?345888-TB-Developments-3-5-quot-Exhaust-System

 

Tim based the mid pipe and system on the Amuse exhaust, if I was wanting one that is where I would be heading.

 

Another option is the RSR exhaust, very popular on here.

Honestly mark with a UK spec like yours id put the oem cat back on and get a new tip and screw from toyota

 

I do agree Kev but I actually like the completly stock look with a nice big back box

It’s easy to swap back to oem (I have an oem one in the loft)

My red Uk tt6 car has the oem exhaust but I like the little extra noise on one of my cars!

Thank you for your reply

I have a nur spec (no cats) in my mkiii turbo Supra and love it! On the Ti does it have a rounded back box as that’s the look I like.

As I said I am going to stick to the super dragger for now plus I had it shot blasted last year and rust proofed and painted as the pipe work is mild steel unlike the nurspecs stainless.

I have the HKS Hi Power Racing with its 94mm pipe on my car and its really quiet on the inside but people say it sounds the part from the outside. There are both cats in place on my car. I prefer it to my old 3 inch bespoke MIJ exhaust that was a lot louder and very boomy on overrun, maybe its an age thing?

People have said exactly the same about mine I even moved it on my drive without the back box on and it’s still pretty quiet.

I think it’s an age thing especially you! but I am getting there too
