Okay im orderin my hooker supercomp long tubes tomarrow and then maybe in a few weeks im goin to order the mufflex y pipe for them and the part number is TPI-Y and im goin to put it back into my hooker catback and the redoucer they say i would need to do so is R400300. i was woundering for the people who have gotten the mufflex y pipe. is that the right part number i listed above? if so thanx.

Sorry, I can't find my reciept, but the Ypipe I have is the one they said I would need. On the web page they used to only have two listings, one with O2 sensors and one without. I hope this is helpful.

well i dont need the pipe with the 02 sencors becuz im sure the hooker supercomps come with the o2 bungs on them but ill make sure of that when i get them.

I have all this stuff. The 2210 Hooker SC LTs did not come with O2 bungs. Maybe they can be ordered that way, but mine did not. I ordered the Mufflex TPI-Y WITH O2 bungs so I could monitor A/F ratio, even on a carbed car. I use an Autometer gauge and switch between the two sensors. I use the y-pipe by itself at the track and use a Dynomax Bullet muffler on street.........

Thanx Phil. also does the pipe end where the intermidate pipe would be if i was runnin a single 3in exuast system? becuz i wanna run the y pipe and headers back into my hooker catback.

The ypipe ends in the passenger side of the tranny tunnel. It can join up with your 3in intermediate pipe there with no problems using the reducer you mentioned. www.mufflex-performance.com

I just put a group purchase together with Mufflex Performance. The savings is 15-20%. I fear that one of our participants is going to drop out, leaving us no choice but to cancel the GP. If you are interested in being in the GP, please shoot me an email at jmatlock88@aol.com. Thanks!

well ill have to get back to u on that GP by like late next week becuz i get paid on thursday. also how would the GP work. like do i send u the money or do i send it to mufflex and tell them its part of a GP or something.

Your 3" I-pipe will not just hook up to the mufflex reducer without some modification in length and location. A few bends may be necessary as well at the exhaust shop, I doubt anyone can do it at home w/o shop type tools and gear...........

I've had my setup for like two years now............I'll never go back to shorty headers...........

Dude your chassis is so clean, how many miles??

135,000 miles on my '87 IROC, all miles in CA and AZ, dry weather! Interior of car looks even better!!

Just got my NOS kit, I should be deep into the 11s very soon................

Woah, cool!! Sometimes mileage doesn't matter, you've taken such nice care of it.

Your cars look great!!

Did you see my red '89 IROC L98 for sale!! It's in better shape than my '87!!!!??? Go to Classifieds.

did u have to do anything to ur crossmember or no? becuz ive heard for the y pipe people had to modify there cross member. i think.

i just hope the exuast shop doesnt rape me in price if i try to get it to go into the intermidiate pipe.

Crossmember edges were notched to allow for more clearance..........not a big deal.

did u reenforece urs when u notched it or no?

Yeah about the crossmember thing. If you have an aftermarket crossmember the Mufflex Y-pipe might not fit anymore. I switched over to a Spohn crossmember and torque arm and my y pipe would not fit because it is much more rigid design. No big deal, just had my local exhaust shop bend me one. I know its not what you are asking, just something I found out the hard way

thanx for the tip. i was thinkin of gettin the sophn torque arm and would i need the crossmemeber for that or no? if i do ill just get the BMR torque arm if thats the case

Yeah the Spohn torque arm and crossmember come as a kit. They design it (Torq arm) to mount to the crossmember rather than the tail of the trans. It works great, I think. Only problem I had was my exhaust needed to be reworked.

BMR does make a few different varieties of torque arms. Their highest level piece also changes the front mount from the trans to the crossmember. They make a bolt in arm if that is what you are looking for.

i kinda just wanna do my exuast once and do it right for now. i think ill just look at the BMR torque arm that bolts into the stock location or ill just keep shoppin around to see whos is good and what will work with my exuast setup after i get the headers and y pipe
