Hi. As above, I am looking for a track friendly back box or catback system for my Classic Sti.
Running fully decat ATM with resonated centre but I have recently damaged my TSL Group N back box so new one is needed. I have 3" bellmouth downpipe so it would be great if centre and backbox will be also 3" BUT track day friendly.

I am not looking for something very expensive because smashing rear of my car by hitting a tree will cost me £700 to be repaired so...


Thank You

 

Iv got a Titanium back box with resonated centre section 3inch but I think the flanges are 2.5 but if you're interested I'll look tomorrow. I'm told it's a quality system the box says TI on the back of it. It was on my V3 STI but was too quiet for me so swapped for a Cobra. There is a divorced downpipe too with it. Not really sure what it's worth but I'm guessing about £200.

 

i have a 3" hks legamax backbox. pm me if interested.

 

RICHARD,
Cheers mate but I'm looking for something definitely cheaper than that, plus I have the downpipe already so...

99greenwagon,
Will send you a PM shortly buddy

 

No problem, let me know if you change your mind, I can knock the value of the down pipe off if that helps.

 

i have a aps back box 3" in vgc £100 + delivery

 

mazmike,
Do you have any pictures of this back box or maybe a link to some website so I could see how does it look and read about it ?

Cheers

 

Hi mate here's my 3" powerflow system, haven't decided if to fit this or my 3" Jasma yet, but one will be forsale

 

Hi.Would this pass track noise level ? As I said, downpipe is also decatted.
Price ?

 

Not sure mate, i'm running sports cat on my Jasma and its not that loud. Be eaiser to get 2.5" with resonated box

 

SORTED :-)
Thank You guys for all offers.

 

I am also after a classic back box suitable for the track. What do you guys still have available?
