I just installed my new custom Catback exhaust its 3" straight pipe with dual 2.5" pipe at the end, no muffler, no resonator, Stock CAT.. Now the car backfires alot "or i think correct term is afterfire ?"
Will this cause any damage to the turbo? or the engine? car is stock besides the exhaust.

 

Wait until you remove the "CAT" lol
Don't worry just get a tune.

 

In need of a tune.

 

Even with an off the shelf AccessPort tune (Perrin Stage 1), after I installed my Perrin CBE I notice the occasional small "pop" every now and then...no backfire...just a small hiccup. I think sounds like this just come with the territory when installing an aftermarket CBE.

 

No worries. Don't you like the attention? haha

 

A tune will help a bit but you'll still get it. I kinda like it

The best is now you WILL be throwing fireballs/flames if you gun it and then let off the gas.

 

Thanks for replying all... i dont seem to get any flames yet just sparks, if i was to get HFC would that make it flame? i have been looking at UR HFC. test pipe is a no go, with the fine of 15k AUD .

 

Tune isnt going to fix it. It is just what these cars do with exhausts.. with a test pipe its even worse. You should hear my car... it pops all over the place.

 

Does it pop at open throttle too? or at close throttle only?

 

enjoy your new exhaust you have no worries

 

Get tuned budy

 

I love that popping, I don't know what your talking about, "op". I was disapointed when I first bought the car and it was so docile.

 

HFC should not make it flame at all, most likely it will limit backfire a lot more than test pipe.
+1

 

I'm right there with you. I draw wood when my car backfires.

 

3" HFC comapred to stock CAT should make some sort of a improvement ?
