[alex]

Hi everyone next week i finaly will be able to set my full exhoust 2". But.... i was promoted at work and i havnt started yet on my new position. I dont gave much $ to spend. So i wanted to know if i can start doing my full exhoust 2"" and leave the 1.75 muffler? Can i do that? Will i still loose HP? or leaving the stock muffler with 2" exoust helps my compresion? Let me know Tips Thanks!!. Oh i have header on my car. So the 2"" will start from the header'r end. Removing all resonators and making all 2". thanks and take care

i think the muffler is the most restrictive part of the exhaust, so i would start on that end if you are not doing the whole thing.

then when you have more money replace the middle pipe.

yeah i would wait myself and do the whole thing at the same time, im going to buy another set of headers and run 2.25 or 2.5 pipe to a high flow muffler, nothing in between

rabbit, i got my job and i worked lol, ill send you that money next weekend

The most restricted part is the header. Its way too small and short before it merge. It gave me the biggest power increase before I did anything to the engine.

I would say 2 inch is too big.

I am using 2 inch straight through last time. Even with 155hp and 201Nm I find it ok only. Any RPM below 2.5k is a pain. Too draggy. You need to keep rpm high constantly for better response.


Now I am using 2 inch straight thru with a straight thru muffler in between, and a 2 inch semi flow rear muffler (due to noise, my local cops like to catch illegal exhaust, and each time is a hefty near $600US fine). ANything other than original is illegal. If we want legal one such as fujitsubo or N1, super sprint, remus...etc it will cost abt $1000US+ including the certificate to certifity its approved by the authority. Its all about tax. That cert cost $800+US. The muffler only cost $200+US.

The only thing on the exhaust that I see changing is the header, just because I like a quiet car, and leaving everything else. But I also like power... but then again who doesn't?
