i been looking at websites, to see if any exhaust for a crx is 2.5" piping. i called a few places the past week, and they only carry 2.25" catback exhaust, i did hear that skunk2 might have one on the market that is 2.5", but no one picks up when i call. also if anyone has a 2.5 catback exhaust system on there crx, please post pics or info on how it was done and how sounds.

thanks alot all

 

Thermal Tech has a 2.5 I believe.

But the difference really isnt that great if its just for street use.

the Thermal tech is and awesome exhaust system, good sound and good gains. same set up as stock (muffler in the middle). Down side is no silencer capabilities.

also look at Tanabe ~ the Hyper medalion is there best line for gains. (gold and silver lines too). They offer a louder sound (still a nice one), and they come with a silencer. It also has more of the "traditional cylinder" look of most cat-backs / mufflers which I kind of like.
(the resinator is pushed back to where the muffler used to be).

Both will run you about $500 msrp.

 

Alot of companies do. But you just have to look under TURBO catback exhaust, not ideal for NA though

 

These guys have them.

The Skunk2 system has 2.5 inch piping when measured from the outside, but the inner diameter is actually smaller.

I disagree. 2.5inch exhaust systems become necessary on N/A set ups, when higher compression, bigger cams, and free/er flowing heads are introduced. They do make a difference in performance.

 

The Greddy MX is 60mm. 60mm = 2.36" which is bigger than 2-1/4 but not as big as 2-1/2. I like mine.

my friends friend is selling the tanabe super hyper medalian or some ish full cat back selling for 250. i think i might go for it. I dont want it too loud tho. but i want a good sounding exhaust.

it depends, for the avg person, you're definetly not gonna be needing a 2.5 in exhaust, even w/ a b16 w/ say cams, head work etc. when you move into a motor w/ more displacment, 1.8, or 2.0 liter. thats when you'll definetly want to step up the header (dtr, anr, hytech etc) because headers like the jdm itr become very restrictive...and you'll also want to move up from that 2.25, or 2 3/8 to a 2.5

B16 w/Jun III's, CTR pistons, bolt on's and Hondata, saw a 7hp increase peak (about 7700) due to a larger, mandrel bent 2.5 exhaust system, including a change from the US DC 4-1 header, to a JDM DC 4-1, and Turbo N1 muffler. It does of course depend on the set up, as I mentioned above, but I feel that saying "2.5 is way too big for N/A" is somewhat misleading. Just my experience, and my opinion.

so the b16 picked up about 7 hp around 7700? i dont doubt that one bit, but you said that they switched from the usdm dc 4-1 to the jdm dc 4-1 and the 2.5 exhaust? i think that the majority of those gains came from the jdm dc 4-1. the usdm dc headers really suck *** compared to the jdm dc, or compared to any header that uses a 2.5 collector for that fact of that matter.
