GT4 Exhaust Help Needed, Cant fit it Options

[3SGTE]

Bought a stainless steel cat back exhaust for the gt4, a mongoose to be exact. i took it to my local exhaust garage, a well known garage, and they told me to fit the exhaust you need to drop/lower the rear subframe and possibly the front just to get the exhaust fitted.
Is this true?? plus the stock exhaust is ovaled at the front subframe to fit snug, and the new s/s exhaust system isnt, will this make a difference?
Thanks guys!!

i have the mongoose system on mine, was the 1st thing to be replaced...had no problems at all fitting it...did have to cut the front section of the kakimoto system to get it out, but the goose went in with out any issues at all...slide in, slide out While that was being done took the cat out and fitted an xspower decat...rumbes and pops nicely now...dreading the MOT next month..lol, have a feeling the cat will need to go back in for a few hours...will give me an excuse to lagg the decat though...

mine is 3 bolt at the front, on the front pipe.. what does that mean then? how come yours were two? did you change your cat?

Standard cat is 3 at the bottom, u will need some bolts to put it all together unless they came with it..Oooo and possibly a new gaskett..the goose supplied from fensport comes with nothing at all...if u are replacing any bolts i would go either stinless steel or titanium...no rusting ;D no grinding to remove them ;D
