Help...Racebox or TSL Group N back box
 

Hi, I'm trying to choose a new back box for my blobeye STI which is otherwise completely standard.

My STI doesnt really burble and I want to get back the flat four burble that I had on my old blobeye WRX which had a WR sport backbox on it.

It really MUST be quiet with no cabin noise when cruising. I just want a nice burble when driving around town and accelerating etc. so I need something not too outrageous!

I've narrowed it down to either a Racebox from Scoobyworld or a TSL Group N. At the moment I'm leaning towards the TSL as it's bigger - 4 inch exit -and quite a bit cheaper.

What would you recommend?

tsl all day long , had one on mine ! perfect fit , look 100% and sound great (not to loud) gives a nice deep burble on idle too !

Thanks SNAP-ON, did you fit it yourself?

I had a Racebox and it is louder than the TSL

Yes only two bolts and three rubbers ! 15 minutes - easy , or take it to an exhaust center and bung a fitter a tenner ! i will fit it for ya if ya near brighton !

Thanks, I'm only about 45 miles from Brighton in Surrey but I guess it'll be quicker to nip to local exhaust centre or do it myself, thanks for the offer though. Did you need a gasket on the flange or any paste or anything?

Just get a new gasket when you order your back box , they normaly ask you if you want one anyway , there only a couple of pound so worth it ! i just pasted mine up ! good luck and welcome to the burble !

TSL Group N is the best 'non-Jap' style backbox on the market IMHO.
I've had one on the car for 4 years. Infact I had it on the previous Scoob for about a year and took it off when I sold the car on. So must of had it for about 5 years now.

Ok thanks for all the replies guys. A TSL Group N it is then!! I'll let you know how it goes.
