QTP Headers vs. SLP LT's I have a question that some may consider rather dumb. I have the SLP lt headers with RT cats and Magnaflow catback. I've been doing a lot of reading on the QTP's. Next spring, I plan on a H/C swap. Do any of you think that a swap from the SLP's to the QTP's would provide a significant increase in performance, HP and torque? Would a swap like that really be worth it?

Re: QTP Headers vs. SLP LT's Try doing a search on "SLP headers" and see what you can find. I know I've seen a few posts that showed good gains on big H/C motors by switching from SLP to QTP/Grot. headers. Not really sure what SLP was thinking making those headers so twisty trying to get the primaries all the same length.

Re: QTP Headers vs. SLP LT's O.k. I see someone one else as sort of the same situation as me. I am still stock manifolds and am trying to determine which header to get. I have a 2000 Hawk. I do not race it it sits in the garage most of the time. I am wanting to go with QTP and found out if I use there Y and cats I might have to cut the I pipe. If I go with SLP I won't have to do anything. I Know people really bitch about the SLP but I have a car I do not want to cut up to put an extra 5 horses in. How about that added to the topic.

Re: QTP Headers vs. SLP LT's So leave it stock if you don't want to "cut it up." It's just a piece of exhaust pipe. It's not going to devalue the car anymore than just installing headers.

Re: QTP Headers vs. SLP LT's Sorry, Did not have time to finish post and did not want to take over the thread. Cutting the I pipe is a factor. The car is a 2000 formula hawk. According to SLP 1 of 1 with my option's and 1 of 2 white formulas from 2000 and only 1 of 47 formulas made that year. O.k. so it sound's **** but if the time comes I want to return it to stock I do not want to weld a piece to the I pipe. Plus if I wanted to leave it stock I guess I would not have asked the question. I guess I should have asked if you went with the QTP and catted Y do you have to cut the I on the SLP Dual Dual. I like those more than SLP but the SLP you do not have to cut the I. Thanks for any smart *** comments or from help from the real users out there.

Re: QTP Headers vs. SLP LT's Um... hear'sa thought.. remove the stock exhaust that will eventually rust all together and put on something aftermarket from the long tubes back.
The elements always do the damage to exhaust piping first.

I have the QTP's on my car, and I've also kept all my stock pieces as well. In the highly unlikely event I ever get rid of this car, they'll be around to be reinstalled, and no one will care anyhow. If you're that concerned about the I-pipe, I'd suggest you replace it now to preserve it from the elements. I got the headers on my Firehawk because I wanted to keep my y-pipe from prematurely rusting. :p

Re: QTP Headers vs. SLP LT's Let's see, I asked about the QTP's vs. the SLP's which I already have on the car. Someone starts talking about an I pipe and whether or not to cut it and 6 out of 18 responses are about my original post the rest about this I pipe and whether or not to cut it. For those that responded regarding my question, I thank you. For the others, well, if you want to discuss something else why not start a new post.
