Hi everybody. Im new to HT so i hope to learn from u guys. Anyways i just got my 2001 2dr teg LS. Its all stock at this point (bsides the intakes). My 1st mod i want to do is exhaust system. I want to go with the BC spec 2. I heard this system is pretty loud but it sounds good, wut do u guys think? Well i did some research and found out that the BC spec 2 system has a 2.38inch piping only NOT 2.5inch. So does that mean i have to get a headers with 2.38inch collector and 2.38inch hi-flow cat too? Or will the 2.5" headers collector will be fine?

BTW what is the collect size for dc headers? How come i kept hearing people saying the dc JDM 4-1 headers has a 2.5inch collector.... theres a JDM for DC??? i thought all DC are the samething? Wuts the other size collector then? Can u guys clear up. THANK YOU all very much. Im hoping to get this clearified and get started on my car. Ill post up pix when its ready.

 

jdm size is 2.5 others are 2.25

 

OOs thnx for the reply. So should i go with a 2.5" header + cat and bc exhaust? Or should i stick with the 2.25" headers collector? BTW i can't find any hi-flow cat with a 2.38" openning that connects to the exhaust. THANKs
