A few weeks ago I had my Edelbrock Rpm series exhaust installed. While at the exhaust shop I monitored the installation and everything seemed to fit pretty good. The only concern was the slip fit from the I-pipe to the over-axle pipe. It created a lower than normal area in the system. The tech tried his best to get it to fit higher, but with no luck. Just wondering If any thirdgenners out there had the same issue with that system. And if so, did you modify it to get more clearance. Time to drop ol' Vic a memo I guess.....thanx.. Oh yeah, way cool exhaust sounds from the rpm series I'd say.

Most 3" cat-backs have to rest right on top of that brace that sits above your panhard rod. You should be fine as long as there is some space between it and your axel.

Sorry to confuse you, I 'm talking of ground clearance....Axle clearance and suspension clearance is fine though..thanks

Oh okay I see what you mean. I think everyones is like that. My hooker sits pretty low and I know a lot of other peoples do as well. Some have gotten their 3" exhaust to tuck up a bit better but I think they just had the knack and got the allignment just right.

Well, I'm Vic, but my last name isn't Edelbrock

I have the 3" system on my RS, an I've taken it on, and off many times, I had the same problem you are refering too (but not on the first install)

I chop sawed alittle of the inter pipe to get it to fit in easier, i also sanded in down a tad to get it up as high in the over the axle pipe as possilbe, it fits great now, doesn't go any lower than the torque arm

Thanks for the info Vic, Well, the shop welded mine there at the fit... and I've yet to notice any curb or speed bump scrape... I'm going to have them refit the I-pipe this year sometime when I go back in for a y-pipe tie in. Just no reason for it to be visible a distance out from the car..

I had the same cat-back on my car a while back. I experienced the same exact problem you desribed. Right where the I-pipe made the turn to go up over the axle was the lowest point. Mine scraped a few times so I decided to cut a little off the end of the I-pipe to get that bend a little higher.

Just like was mentioned above.

"NOTE: Due to large production tolerances on GM F-Body, it may be necessary to trim the overaxle pipe at the muffler inlet end. (Caution- There needs to be a minimum of 2" slipped into the muffler for proper clamping). Tailpipe centering can be affected by how the muffler is positioned in the chassis. Muffler should be parallel to rear axle. Trimming of the tailpipes at the muffler can also be used to adjust tailpipe centering."
