Carpentervs. Jardine
I have slash cut black jardiness on my R3R and they sound OK , I LOVE carpenter race, how-ever their headers are made to compliment their high compression engine-more air in needs more air out.they are loud race engine headers (recommend their 240 RWHP kit) If you have a stock compression engine, and plan to leave stock compression I would suggest not to go Carps. they will only let people for miles around you have a stock engine! I may be selling my Jard's. over the winter.send me a PM if interested.
