Hello all,
I recently had a TSL Firestorm Exhaust fitted to my 03WRX. The sound is now incredible and I'm really pleased with it, but I have to say the car feels like its lost some of its zip. Is this normal after having a large exhaust fitted? I'm new to all this so excuse my ignorance!

It feels like I have to drive it harder to get the zip I used to get with ease. I've mentioned this to someone whose no Subaru Mechanic, but knows a damn site more than me, who said it probably needs tuning!

Does this sound right????

Also, anyone know any Car Tuning places in the Manchester area ???

Thanks

From everything I've read about turbo cars the last thing you want is back pressure. Fitting a high performance back box will remove some of the back pressure which is good for performance. It allows the turbo to spool up quicker and the exhaust gases can exit easier.

A backbox won't make a massive difference but if you removed the centre silencer and the 2nd cat you would need to have the ECU remapped to really take advantage of the reduced back pressure.

maybe the new exhaust is more restrictive than the one it replaced?

The stock system will be way more restrictive than the TSL Firestorm. Subaru have to worry about noise regulations etc. TSL don't.

to be honest I noticed nothing at all when I put a fire storm bb + centre section on my bugeye wrx - noise is a funny thing, it can make things seem slower or faster I now have a hks hiper, it always feels quicker with the bung in but I know its not as Im hitting the same speeds.. just enjoy the rumble and try not enoy the neigbours
