No prob! I'd look for a used one. I sold mine for $70 a few years ago when I upgraded my coupe's exhaust. Ebay...Craigslist...or this forum!

6MT's also do well with a plenum spacer mod. For even more, the Motordyne lower plenum will give you some decent gains!

Deleting the resonator will make it sound raspy...do some youtube searches with it and you'll see. Spacer + Lower plenum is an awesome mod! The R2C is also sweet...I love mine!

ohhh okay now were on the same page. i was thinking lower plenum and spacer were different things. you mentioned an intake spacer on the very first post i made on nico. ive heard of obx throttle body spacers but i think thats different than what you were talking about unless an intake spacer is the same thing as a lower plenum spacer

hey i forgot to ask you does the midpipe go all the way to to the muffler? i have a muffler delete on my car and the custom axleback section i have is welded to a pipe that leads to my resonator and from what i can tell, if i get the coupe/fx35 midpipe, im gona have to get another axleback section and new tips, right?
i have a picture but idk how to get it on here

Hi-flow cats will give you more exhaust noise while freeing up some power as well.

i already have stillen race pipes. i thought about the hfc's but i decided id be daring and get the "off road use only" race pipes. i see you have wheel spacers listed on your mods. will my car look stupid if i get wheel spacers for it with the stock suspension? i just want the wheels to be flush with the quarter panels. im planning on getting coilovers this summer

I agree with Joe, I did a resonator delete and it sounded very raspy and more like a sportbike than I liked. Just for info sake, I recommend staying away from headers unless you plan to run over 3k to 3,500 rpm ALOT or race tracks with it. The install is a pain on the pass side and you lose alot of lower rpm oomph. IMO I think the hfc's sound much better than the "test pipes" or free flows that you have, I took mine off and installed some Kinetix hfc and am very pleased with them. Lowered the high pitch sound to a deeper tone. Then, of course, I jacked that sound up by installing a cheap azz true dual exhaust system. :gapteeth: It sounds great cruising nice and slow then all heck breaks loose when I floor it, a little tinny and high pitched. then again, it is a 6 cyl.
